Since its observation discovery in the 1990s, dark energy has been one of science’s biggest mysteries. Could black holes be the cause?

When your passion becomes your day job, sometimes the day job becomes a chore.

Voyage into the lawless world of experimental literature.

The scientists are headed “straight to the FDA” to begin human trials.

In theory, dark matter is cold, collisionless, and only interacts via gravity. What we see in ultra-diffuse galaxies indicates otherwise.

Godfrey Hounsfield’s early life did not suggest that he would accomplish much at all.

Although it’s often described as the Amazon of China, Alibaba has a radically different business model that does not rely on inventory management.

There are two different ways to measure the expansion rate of the Universe, and they don’t agree. And no, new measurements don’t help.

Scientific surprises, driven by experiment, are often how science advances. But more often than not, they’re just bad science.

The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?

So far, gravitational waves have revealed stellar mass black holes and neutron stars, plus a cosmic background. So much more is coming.

Mutations that confer malaria resistance occur more frequently in people who live in regions where the disease is endemic.

Known as primordial black holes, they could thoroughly change our Universe’s history. But the evidence is strongly against them.
